I commented further down, but this is already the case. The U.S. has this, many high schools have trade programs. You're still "technically" in school you spend your junior and senior year at a trade school and often working / making money (some as early as sophomore year) Unfortunately, this is only true for places with trade schools nearby. I grew up outside of Chicago and every school had this option.
